Why do people disrupt traffic?

[Deja Q]

You know. Putting up big signs and flags of things they believe in, in the middle of busy streets; usually at busier street light intersections?

For example, I don't need to see an anti-UN flag flying underneath Israel's flag in the middle of a very busy major street where there's 50 cars on each side 0f the median going 50MPH... :eyes:

There's a time and a place. Trying to cause auto accidents is not really one of them.
